White noise has equal amounts of all frequencies. We hear the HF
dominate because higher frequencies have more energy. (And because our
ears are more sensitive to it).

Ears are most sensitive around 1k, aren't they?

Probably. I wasn't thinking hard about that, I was just caught by the
claim that HF dominates white noise in the audio band, when white noise is
defined as being made up of all frequencies present with equal energy in
each.

Hmmm...equal energy means that it would be more energy per octave at
higher frequencies, right?
